The gradual unbalancing of a game due to successive releases of new content. The phenomenon may be caused by a number of different factors and, in extreme cases, can be damaging to the longevity of the game in which it takes place. Game expansions are usually stronger than previously existing content, giving consumers an incentive to buy it for competitions against other players or as new challenges for the single-player experience. While the average power level within the game rises, older content falls out of balance and becomes regressively outdated or relatively underpowered, effectively rendering it useless from a competitive or challenge-seeking viewpoint. Very occasionally may refer to the result of repeatedly balancing a game primarily through buffs and nerfs, thus making every character substantially more powerful than they were at release.
